The other problem with pool DE is the silica content. It's uber-high in the pool version and isn't safe (think of those silica packets that come in a box of shoes or whatever to prevent moisture - they flat out say Toxic, do not eat). There's alot less silica and like you said, its treated differently in food-grade.
